OK, I followed with updated tutorial https://github.com/opencog/atomspace/tree/master/examples/rule-engine/chaining and I managed to run my first cog-fc with the normal result. I would like to raise two points:
1) tutorial says that cog-fc has 4 arguments, but my version of opencog (as or start of 2017) of cog-fc still has 3 arguments: source/rule base/focus set. There is no variable-declaration argument. Just wanted to note for those who use this thread for troubleshooting cog-fc. 2) *I wonder about necessity of source as an argument, why we need this? *Business Rule engines (like JBoss Drools) use entire Atomspace working memory as domain for reasoning - somehow first rule is selected and matched with facts and first inference is made and so this process continues? Focus set can be emtpy Set and then the entire Atomspace becomes the focus set. Maybe we can do this with source as well - maybe empty source will designed entire Atomspace as a source? -- You received this message because you are subscribed to the Google Groups "opencog" group.
